Ingredients
-
3–4 lbs beef chuck roast
-
Salt and black pepper, to taste
-
2 tablespoons olive oil
-
4 large yellow onions, thinly sliced
-
4 cloves garlic, minced
-
2 teaspoons fresh thyme leaves (or 1 teaspoon dried thyme)
-
2 teaspoons Worcestershire sauce
-
2 cups beef broth (low-sodium preferred)
-
1 tablespoon Dijon mustard
-
2 tablespoons tomato paste
-
3 medium carrots, peeled and cut into chunks
-
3 celery stalks, cut into chunks
-
2 bay leaves
-
2 tablespoons cornstarch (optional, for thickening)
-
2 tablespoons cold water (optional, for thickening)
Directions
-
Prepare the roast: Pat the beef chuck roast dry with paper towels. Season generously with salt and black pepper on all sides. This ensures a flavorful crust when seared.
-
Sear the meat: In a large Dutch oven or heavy-bottomed pot, heat olive oil over medium-high heat. Once hot, sear the roast on all sides until browned, about 3–4 minutes per side. Remove the roast from the pot and set aside.
-
Caramelize the onions: In the same pot, add the sliced onions. Cook over medium heat, stirring occasionally, until they become golden brown and caramelized, about 20–25 minutes. Add the minced garlic during the last 2 minutes of cooking.
-
Build the French onion base: Stir in the tomato paste, Worcestershire sauce, Dijon mustard, and thyme. Cook for 1–2 minutes to combine flavors and slightly deepen the color.
-
Deglaze the pot: Slowly pour in the beef broth, scraping the bottom of the pot to loosen any browned bits. These bits add incredible flavor to the sauce.
-
Add vegetables and roast: Return the seared roast to the pot. Add the carrots, celery, and bay leaves. Bring the liquid to a gentle simmer. Cover the pot with a lid.
-
Cook low and slow: Reduce the heat to low and cook for 3–4 hours on the stovetop, or transfer to a preheated oven at 325°F (163°C) for the same duration. The roast should be fork-tender and the vegetables cooked through.
-
Optional thickening: If you prefer a thicker gravy, remove the roast and vegetables once cooked. In a small bowl, mix the cornstarch and cold water to create a slurry. Stir this into the liquid in the pot and simmer for 2–3 minutes until thickened.
-
Serve: Slice or shred the roast as desired. Serve with the rich French onion sauce and roasted vegetables, accompanied by mashed potatoes or buttered noodles for a complete meal.

FAQ
1. Can I make this in a slow cooker?
Absolutely! This French Onion Pot Roast adapts beautifully to a slow cooker, making it perfect for busy days when you want dinner ready with minimal effort. Start by searing the meat in a skillet to lock in the juices and create a flavorful crust. Then, caramelize the onions in the same pan to bring out their natural sweetness. Once the meat and onions are prepared, transfer them to your slow cooker along with the broth, vegetables, and seasonings. Cook on low for about 8 hours, or on high for 4–5 hours. The slow cooking process ensures the roast becomes tender and melts in your mouth, while the vegetables absorb the rich French onion flavors. For best results, avoid lifting the lid frequently, as maintaining a steady temperature helps develop a deeper, more concentrated flavor.
2. What can I serve with this pot roast?
This dish pairs perfectly with classic comfort sides that soak up its rich, flavorful gravy. Creamy mashed potatoes are a natural choice, creating a luscious base for the roast and sauce. Buttered egg noodles are another excellent option, adding a soft, chewy texture that complements the tender beef and caramelized onions. Steamed rice can also work well if you prefer a lighter starch to balance the richness of the meat. For a touch of rustic charm, serve with a fresh crusty baguette—ideal for sopping up every last drop of the French onion gravy. You can even add roasted or steamed vegetables like green beans, broccoli, or brussels sprouts to round out the meal and add color to your plate.
3. Can I use a different cut of beef?
While beef chuck roast is recommended for its marbling and tenderness, other cuts like brisket or round roast can also be used. Keep in mind that leaner cuts may need a longer cooking time to achieve the same level of tenderness. If you opt for a leaner roast, consider adding a bit more broth to prevent the meat from drying out during slow cooking. The slow-cooked French Onion Pot Roast works best with cuts that have some fat content, as this helps enrich the sauce and ensures the meat stays moist and flavorful throughout the cooking process.
4. How can I thicken the gravy naturally?
If you prefer a thicker, more luxurious gravy without using cornstarch, simply reduce the cooking liquid. After removing the roast and vegetables from the pot, simmer the liquid uncovered for 10–15 minutes over medium heat. This allows excess liquid to evaporate while concentrating the flavors. The result is a naturally thickened, deeply savory French onion sauce that coats the meat and vegetables beautifully. For an extra layer of richness, you can swirl in a small pat of butter or a splash of heavy cream at the end. This simple step elevates the dish and gives your gravy a velvety texture that’s irresistible.
Final Thoughts
Homemade French Onion Pot Roast is a dish that delivers both comfort and sophistication in every bite.
